FIELD OF INVENTION

The present invention relates to a rotatable platform riser system usedfor capturing imagery of objects from one angle or multiple angles witha seamless white background.

BACKGROUND

A 360-degree object photography turntable is a tool used byphotographers and videographers to capture imagery of objects rotatingin a circular 360-degree motion. This kind of turntable is fundamentallya Lazy-Susan; it typically has a flat, circular-shaped turntableplatform which revolves around its vertical axis 360 degrees and can bemanually rotated clockwise or counter clockwise. A digital photographycamera or video camera is secured on a stationary tripod and aimedtowards the object(s) resting on the turntable platform. The turntablemay be motorized and computer controlled to achieve a higher degree ofangle precision and overall production speed while enabling hands-freecapture automation.

An object to be imaged in 360 degrees is typically placed on theturntable platform. The object may also be placed on or secured to aspecialized Riser with Riser Platform attached to the turntable'srotating turntable platform. A motorized, computer-controlled turntablewill rotate an object until it reaches the next desired angle. Ittemporary pauses at the desired angle while sending a digital signal tothe camera to capture a photo. Pausing the platform for each capturemaximizes image sharpness by preventing motion blur. Once the photo iscaptured, the turntable's platform rotates the object towards the nextdesired angle to capture the next photo. The rotating platform pauses atevenly spaced angles for each individual capture. This ensures theresulting 360 view's rotation is steady, consistent, and precise. Theturntable continues this rotate/pause/capture sequence until all of thedesired angles are captured.

Capturing many photos with small platform rotation increments yield a360 view with a smooth rotation appearance, whereas capturing lessphotos is faster to produce and reduces load time on a website. A 360view on a website can contain as few as 6 individual images or as manyas 720 individual images, however most 360 views range between 20 and 72individual still photos captured with a digital photography camera.

It is also possible to produce a 360 view of an object using a videocamera. This less common method is done by recording a video of anobject rotating continuously on a low-speed motorized turntable. 360degree imagery derived from video recordings yield moderate motion blur,higher image compression, less overall sharpness and lower imageresolution. Low-speed continuous motorized turntables are less expensivethan computer controlled turntables, making video capture an attractivelow-cost solution.

The majority of object photos and 360 degree object photos haveseamless, pure white backgrounds without shadows or reflections. Digitalediting is commonly required to remove natural shadows and reflectionsas well as whiten dark backgrounds and hide photography props andaccessories that show up in the background or within the reflections ofthe object itself. A system that captures object imagery requiringminimal digital editing is desirable. A system that captures objectimagery without needing further digital editing is more desirable. Arotating system that captures 360 degree object imagery requiring zerodigital editing is the proverbial Holy Grail. Reducing digital editingis exponentially desirable with 360 degree object photos because eachobject has not one photo, but 20 to 72 individual photos.

Certain embodiments of the present invention are directed to a rotatableplatform riser system which may be used as an extension that attaches toa turntable. It is common for the rotatable platform riser system to beconstructed partially of transparent materials so that almost all-whitebackgrounds can be created during photography and/or video captureprocess. The almost all-white backgrounds are desirable for post editingas the backgrounds are easier to remove. The system may also be used asa non-rotatable riser-alone system for capturing object photography at asingle angle, without a turntable. From here, we will discuss arotatable platform riser system used in combination with a turntable. Arotatable platform riser system is composed of two primary elements: Ariser and a riser platform. A riser typically uses four thin,transparent, vertically oriented plastic sheet or rod supports whichserve to elevate a riser platform above a turntable. These verticalsheets of plastic or rods are connected to a non-transparent frameworkand extend upward from the turntable platform. The bottom of a riserframework may rest on top of or attach directly to the rotatingturntable platform. A riser platform is a thin circular transparentdisc; this serves as a flat horizontal table which an object to bephotographed is placed onto. A riser platform rests on top of a riser.The diameter of the riser platform is sized to slightly exceed thefootprint of the riser's vertically oriented supports. This type ofpartially transparent riser in combination with the fully transparentriser platform, can make the background of object imagery become almostall-white and almost visually disappear when a sufficiently brightbackground is positioned behind it. To achieve this visual disappearanceof the top portion of the riser, multiple photography lights are used.Each light separately illuminates an object for photography and aseamless white background set up directly behind the riser and riserplatform. This allows for capturing object photography with mostly purewhite backgrounds and without the object's shadows or reflectionsappearing on the riser platform itself. Although the current rotatableplatform riser systems are acceptable they have several shortcomings:Vertical edges of the transparent riser supports (sheets/rods) oftenshow up in the white background as they move through the photographframe area during turntable rotation. These vertical edges can causeuneven white areas in the all-white background and are especiallydifficult to edit out when they intersect an object's edges. It iscommon for riser's vertically oriented support edges and non-transparentoutward extending metal framework to stick out and show up within thebackground of photography imagery, thereby substantially increasingdigital editing work. Additionally, the riser's vertical support edgesand non-transparent framework also shows up within the reflections ofreflective objects. It is also common for the riser's verticallyoriented supports to bend, wobble, and structurally collapse whenmoderately heavy objects beyond 10 pounds are placed on the riserplatform. Hence, considering the increasing popularity of turntablesamong object photographers, a need is appreciated for an improved designof the platform riser that does not have the above-identified problems.

For purposes of this invention, the term “photography” refers not onlyto colored or black and white still photography, but also refers to stopmotion photography and videography, to 360 degree object photography, todigital imaging techniques, and to any other known or developed imagingtechniques.

The following detailed description includes the best currentlycontemplated mode or modes of carrying out exemplary embodiments of theinvention. The description is not to be taken in a limiting sense but ismade merely for the purpose of illustrating the general principles ofthe invention, since the scope of the invention will be best defined bythe allowed claims of any resulting patent.

Now referring to FIG. 1 which shows an exemplary embodiment of thephotography turntable according to the present invention. Thephotography turntable includes a turntable body 1 and a turntableplatform 2 operably mounted on a top side of the turntable body 1. Theturntable body 1 encloses a drive mechanism for rotating the turntableplatform 2. The drive mechanism could be an electric motor, such as astepper motor. The motor may be coupled to the turntable platform 2through a direct gear drive. Also, suitable AC to DC power adaptor maybe provided to power the motor. The power adaptor may either be enclosedin the turntable body 1 or provided outside the turntable body 1. Asuitable motor controller may also be provided in the wall of theturntable body 1 for allowing a user to control the operation of themotor. For example, an ON/OFF switch and a speed regulator may beprovided in the wall of the turntable body 1 to control the operation ofthe motor by the user. In addition, sensors may also be deployed toprecisely monitor and control the operation of the motor. Besides,handheld controllers connected to the motor through a wire may also beused. Such handheld controllers may be easier to operate by the user andthe user does not have to reach to the turntable every time for changingthe settings. Instead of the wired connection, wireless connectivity canalso be used to wirelessly connect the handheld controller to the motor,for example, Bluetooth can be used to connect the handheld controller tothe motor.

Further shown in FIG. 1 is a riser 3 mounted on the turntable platform2. The riser 3 is coupled to the turntable platform 2, such as the riser3 could be rotated with the rotating turntable platform 2. The riser 3includes a top, a bottom, and an upright wall extending from the bottomto the top defining volume of the riser 3. The bottom portion of theriser 3 sets on top of or is coupled to the turntable platform 2, whilethe top is open to form a tank-like structure. In FIG. 1 , the riser 3as shown is substantially conical in shape having a diameter of thebottom lesser than the diameter of the top. The height of the riser 3may be varied depending upon the requirements of the user. Similarly,the width of the wall of the riser 3 could also be varied depending uponthe material of the riser 3 and the desired strength of the riser 3.Also, the diameter of the top of riser 3 can be in different proportionto the diameter of the turntable platform 2. For example, the diameterof the top may be larger than the bottom, the diameter of the top may besmaller than the bottom, or the diameter of the top can be same as thediameter of the bottom. Moreover, the shape of the wall may vary, forexample, a straight wall extending from the bottom to the top, or thewall may be curved. Depending upon the diameters of the top and thebottom and the shape of the upright wall, the risers of different shapescould be presented.

The riser 3 could be made of any suitable materials that are known toprovide rigidity and strength. The riser 3 should be strong enough tohold a riser platform 4 and an object. Preferably, the riser 3 could bemade from a material which is transparent, translucent, or white incolor. In case of transparent or translucent material, the white lightmay be used to illuminate the riser 3 as white. Large varieties ofmaterials are commercially known, for example, glass, plastics etc. Itis preferable to have lightweight materials, such as plastics making theriser lighter in weight. A more preferred example of the material thatcould be used in making the riser 3 are polycarbonate plastics.Polycarbonate plastics are light in weight, clear and strong. It isobvious that other suitable materials could also be used without anylimitation.

Over the riser 3 is mounted the riser platform 4 as shown in FIG. 1 .The riser platform 4 is a round shaped sheet having a predeterminedwidth. The riser platform 4 is mounted over the edges of the riser 3,thus the diameter of the riser platform 4 may be either same or largerthan diameter of the top of the riser 3. The riser platform 4 can bemade of same or different material than that of the riser 3. Preferably,the riser platform 4 is made of a transparent or translucent material.On the riser platform 4 is placed an object for photographing. Forexample, FIG. 1 shows an example of the object, which is a cup 6 placedon the top surface of the riser platform 4. The turntable can be rotatedto get the desired face of the cup 6 within the viewfinder of a camera.

Proper photography lighting may be used to illuminate the riser platform4 to get the desired color environment for photography. For example,white color photography lights may be deployed to illuminate the riserplatform 4 in white color. In operation, a white backdrop is placeddirectly behind the riser platform 4 such that a flash from the camerailluminates the backdrop. The illuminated white backdrop is so brightand white during the flash that it makes the riser platform 4 and theriser 3 completely disappear in the corresponding photographs. Anyreflections on the surface of the riser platform 4 also disappear due tothe bright white illumination. The riser platform 4 and the riser 3 areinvisible in the photograph as all the reflections and edges disappearas the bright white illuminates the turntable.

Also shown in FIG. 1 is a floor-stand 5 coupled to the turntable body 1.The floor-stand 5 is used to support the turntable on the floor at thedesired height. The floor-stand 5 can be made of any suitable materialthat is rigid and strong. Preferably plastics can be used because oftheir lightweight. The floor-stand 5 could be removably attached to theturntable body 1, for example, using screws, snap fit and like.

FIG. 2 shows an alternate embodiment of the riser 3, which is acylindrical shaped riser 7. The riser 7 is mounted on the turntableplatform 2 and the turntable platform 2 is mounted on a turntable body1. The cylindrical shaped riser 7 has the top and the bottom of the samediameter. An upright wall extends perpendicularly from the bottom to thetop. The top of the riser 7 is open and the riser platform 4 is mountedover the edge of the riser 7.

Similarly, FIG. 3 shows a dome-shaped riser 8. The diameter of the topof the riser 8 is larger than that the diameter of the bottom and acurved upright wall extending from the bottom to the top. The riser 8 ismounted on the turntable platform 2, which is mounted on the turntablebody 1. The riser platform 4 is mounted over the top edge of the riser8.

FIG. 4 shows a bell-shaped riser 9 in which the diameter of the top ismore than the diameter of the bottom and an upright wall extending fromthe bottom to the top in slightly curved shape up to half of the lengthof the wall, and thereafter curves sharply outwards to form a bell-likestructure. The riser platform 4 is supported on the top edge of theriser 9. The riser 9 is mounted on the turntable platform 2 and theturntable platform is mounted on the turntable body 1.

FIG. 5 shows the turntable platform 2 mounted on the turntable body 1, aconical-shaped riser 3 mounted on the turntable platform 2 and afloor-stand 5 coupled to the turntable body 1. The riser platform 4 ismounted over the top edge of the riser 3. FIG. 5 further shows markings10 over the top surface of the riser platform 4. The markings 10 are ofthe shape of small squares. The markings 10 may be used to alignobjects, to be photographed, over the riser platform 4. Although FIG. 5shows the markings 10 on the top surface of the riser platform 4, themarkings 10 can also be disposed on the bottom surface of the riserplatform 4. FIG. 5 shows the markings in shape of squares, it is obviousthat the markings 10 could be of any other shape, for example,concentric circles. These markings are invisible in the photographs, asthey become invisible in the illumination caused by flash of the camera.

The present invention is advantageous over the designs of prior arts byproviding a durable and break resistant turntable. The photographyturntable according to the present invention makes background solidwhite at all angles which is extremely desirable in post editing. Iteliminates background light halos, which makes the object edges clearand crisp at all angles. Furthermore, it eliminates foreground andbackground reflections due to absence of vertical rods, vertical flatplastic supports, and crossbeam supports etc., as in previous designs ofthe turntable. It can accommodate larger objects due to increasedsupport from the riser. The camera can shoot at higher angle becausealuminum support beams are eliminated. It can hold ten times weight thanprevious designs due to single continuous support edge. The design ofthe turntable is structurally rigid, thus eliminating any wobble. Lesserparts make the invention economical to manufacture. The design of theturntable according to the present invention is structurally rigid, itcan double as a floor stand (when turned upside-down) for the turntableto sit on.
